Donald Trump Jr.'s interview Wednesday with the House Intelligence Committee mainly focused on three areas, sources with knowledge of the interview told ABC News: the June 2016 meeting between Trump, Jared Kushner, Paul Manafort and a Russian attorney; Trump's conversations with WikiLeaks; and past business by the Trump Organization.

At one point, hours into the meeting, multiple sources told ABC News that Trump's lawyers asked how many more questions the committee had. The sources said Rep. Adam Schiff, D-Calif., replied that former Secretary of State Hillary Clinton had sat for 11 hours when she was questioned by Rep. Trey Gowdy, R-S.C., as part of the Benghazi investigation and they were nowhere near that point. It was then that Trump, per the sources, said Clinton's testimony was not the same, since she was testifying about the 2012 attack in Libya, in which four Americans were killed.

Trump declined to discuss details of a conversation he told investigators he had with his father after reports about the Trump Tower meeting emerged, citing attorney-client privilege, according to the top Democrat on the panel.

The sources told ABC News that the committee's questions focused on what information was exchanged during the 2016 Trump Tower meeting in New York City, and Trump indicated the short gathering did not produce any information and ended quickly.

Sources said Trump told investigators he spoke with his father after reports surfaced about the controversial meeting with a Russian lawyer promising dirt on Hillary Clinton. He also told the committee he initially discussed a response with Hope Hicks, a top campaign aide now serving as White House communications director, according to a committee source.

Pressed by Democrats for further details about those conversations, Trump insisted conversations with his father were privileged, sources in the room said. "They stuck to their position that they were not going to share any conversations that Donald Trump Jr. had with his father about the June 9 meeting," Rep. Eric Swalwell, D-Calif., told CNN Wednesday night.

Committee Democrats subsequently questioned the legitimacy of Trump's privilege claim and raised the possibility of seeking a subpoena to compel him to answer.

"The only category of question the he declined to answer were, with respect to any discussion with his father about the June 9 meeting, after the emails had been disclosed publicly," Schiff told ABC News's Pierre Thomas after the interview. "Counsel made a claim of attorney-client privilege. In my view, this is a central communication about a very pivotal meeting and a conversation between father and son is not subject to the attorney-client privilege. So we intend to persist and make sure we get answers to that question."

It's unclear if Republicans who control the committee will join that push.

Rep. Mike Conaway of Texas, one of the Republicans leading the probe, said the interview was "professional" and described Trump as "cooperative at all times."

Trump was also asked about his communications with WikiLeaks after the company reached out to him via Twitter toward the end of the campaign. According to the sources familiar with his testimony, he said his communications were limited to messages exchanged via Twitter and went no further. A Republican source added that Trump was asked about some Trump Organization business going back decades and at times based on old news reports about his father.

The meeting, which lasted just under eight hours, was the longest meeting Trump Jr. has had before a congressional committee. He met with the Senate Judiciary Committee for several hours in September.

The sources added that Trump was questioned by members, with limited exceptions, a majority of whom were Democrats.

Shiff " Your father is a Russian right??? Admit it!" Jr. : "No No No..he's German.....but what about Hillary....Hill....a..."Shiff : " What about your step mother????Does she Sprechen sie Rushkie???"Jr.:" No No....she's transylvanian...I think I dont know..wtf..but what about Hillary...what about Hill....."Shiff : " Junior...have you ever had Russian Goulash....?"Jr.: "no no no no no...what the H_ll..is that anyway? ..what about Hillary? What about Hillary????"That's how that went.

His conversation with his father is not privileged. He is a coward, just like his father. Mueller is just playing with him, he already got his answers from Flynn, he just wanted to see how much Donnie would lie - just like he did with Kushner. It's going to be a Merry Christmas.

Here is a prophecy: "Gather your cymbals America, prepare the confetti, get ready to rejoice and dance and be filled with great joy, let the estactic dancers come forth, as I the Lord am prepared to remove this one out of your house of White light, I will deliever America from the apostate spirit of Jerry Fallwell Jr who has thrown you into dismay. This nasty one sitting in the Oval Office will soon be gone, prepare to flood the streets and rejoice, even more than the end of World War II, I will tolerate no more the wicked Jerry Fallwell Jr and his nasty President. I the Lord will restore your land."

The multiple Congressional investigations are just the appetizers at this clambake. As if ensnaring a former major figure in the Trump administration, Michael Flynn, weren't enough, Special Counsel Robert Mueller is bound to go up the food chain. There's a lot to chew on too. Looking at suspicious meetings tied to Russian influence that Donald Trump Jr. or his agents may have made during last year's campaign is a morsel Mueller can't pass up. With Attorney General Sessions conveniently faulty memory regarding meetings with or about Russians and those presidential memos wanting FBI Director Comey to be dismissed, the main course has yet to be brought out. Justice, unlike revenge, is a dish best served while it's still simmering.

Trump and gang including his son and Sessions are buying time with their refusal to answer questions for one ridiculous reason or another.Why?We need to know why. What do they expect to happen to get them permanently off the hook?

Little Donnie Jr, "Are we having fun yet?" Maybe you should go shoot some elephants in Africa? Poor little boy, wait until they cuff you and daddy and shove your face on the ground. Lock him up! Lock him up! Lock him up! Oh we will grieve when the helicpoters wisk you and daddy out of the White House. Poor beady little eyed thing you. Call up Jerry Fallwell Jr and have him tell you that you have Jesus in your heart...and now you are as 'pure as the lilies of the field' .Maybe we can pay for your security for another snow trip to Aspen, poor little boy. Yes, you will get to dine with Roy Moore and talk about his behavior with minors...so special.
